  • Patent number: 11570243
    Abstract: In a running distributed data storage system that actively processes I/Os, metadata nodes are commissioned and decommissioned without taking down the storage system and without introducing interruptions to metadata or payload data I/O. The inflow of reads and writes continues without interruption even while new metadata nodes are in the process of being added and/or removed and the strong consistency of the system is guaranteed. Commissioning and decommissioning nodes within the running system enables streamlined replacement of permanently failed nodes and advantageously enables the system to adapt elastically to workload changes. An illustrative distributed barrier logic (the “view change barrier”) controls a multi-state process that controls a coordinated step-wise progression of the metadata nodes from an old view to a new normal. Rules for I/O handling govern each state until the state machine loop has been traversed and the system reaches its new normal.

  • Patent number: 11544133
    Abstract: A system and method for dynamic log management of stream processing in a distributed computing environment, such as, for example, a streaming application or stream analytics system. A streaming application can be deployed or published to a cluster, to execute as a client application. A cluster manager coordinates with worker nodes, to commit tasks associated with the streaming application. If a need arises to generate lower-level log data associated with the streaming application, for example to diagnose an underlying cause of a warning/error message, a configuration job can be committed to the cluster to execute as a separate log-configuration application. The log-configuration application operates with the cluster manager to determine the set of working nodes currently associated with the streaming application, and modify the logger configuration at those nodes, to record or otherwise provide log data according to a modified logging level, for example to provide lower-level log messages.

  • Patent number: 11216416
    Abstract: A current state of a dataset is represented by a mutable B+ tree, while each snapshot of the dataset is represented by an immutable B+ tree. An ordering of B+ trees in the ordered set logically arranges those B+ trees into layers, with the mutable B+ tree representing the current state of the dataset being logically arranged as an upper layer, and with immutable B+ trees representing snapshots of the dataset being progressively arranged as lower layers with the oldest snapshot being a lowest layer. Each B+ tree stores dataset records with a strong or a weak reference state; strong records are independent of any lower-layer record, while weak records are dependent on at least one lower-layer record. A snapshot deletion includes merging the snapshot's corresponding B+ tree with its highest neighbor B+ tree, including merging overlapping records based on their weak vs. strong reference state.

  • Patent number: 11157651
    Abstract: A data processing system maintaining a plurality of masking engines is configured to synchronize masking jobs between different masking engines, in order to ensure consistent outputs between the different engines for the same job. Upon identifying a masking job object maintained by a first masking engine to be exported, dependencies of the job object are traversed to identify all objects depended on by the job object, which are used to form an export payload. At least object of the payload is a reference object that references other objects maintained by the first masking engine. When importing the export payload onto a second masking engine, the export payload is analyzed to identify revision information of the referenced object. The identified revision information is compared with revision information of a corresponding object maintained by the second masking engine, and the referenced objects is imported based upon a result of the comparison.

  • Patent number: 11144394
    Abstract: Systems, for managing metadata data blocks, include a fast performance tier and a large capacity tier. The capacity tier stores the data blocks in erasure-encoded stripes. The performance tier stores map data indicating correspondences between logical addresses, associated with a first layer of the system, and physical addresses associated with a second layer. The map data is structured as a B-tree with leaf nodes and index nodes. A method includes determining a volume associated with the leaves. In response to the volume being greater than a threshold, migrating a portion of the leaves to the stripes of the capacity tier. A portion of the indexes that include pointers to the migrated portion of the leaves are updated to include updated pointers to physical addresses of the stripes that store the migrated leaves. A portion of the performance tier that stores the migrated leaves is re-allocated to store additional map data.

  • Patent number: 11132331
    Abstract: Methods and systems for backing up and restoring different point in time versions of a virtual machine, an application, a database, or an electronic file using independently managed snapshot chains are described. In some cases, different point in time versions of a virtual machine may be captured and stored using one or more snapshot chains. Each snapshot chain may correspond with a base image (e.g., a full image snapshot) and one or more incremental files (e.g., two forward incremental files) that derive from the base image. A snapshot chain may be split into a plurality of shards or sub-chains such that the width of each shard or the maximum data size of the files in each shard is less than a threshold data size (e.g., is less than 1 TB). Data operations (e.g., consolidation and reverse operations) may be performed on the individual shards or sub-chains in parallel.

  • Patent number: 11126401
    Abstract: A database server is configured to receive input data which includes a data table. Each record of the table includes a record key and one or more entries. Each of the one or more entries is associated with a corresponding column key of the data table. Instructions are received for sorting the input data according to the column key. The instructions indicate an order in which to sort the input data. Based on the order indicated by the instructions, a pluggable sorting index associated with a column key of the data table is generated. The pluggable sorting index includes the record keys arranged in a sorted order according to sortable properties of entries associated with the column key. A sorted dataset which includes the entries associated with the column key arranged according to the sorted order of the pluggable sorting index is generating using the pluggable sorting index.

  • Patent number: 11093442
    Abstract: Data containers are stored at a first cloud and include file segments managed by a deduplication file system. Metadata containers are written to a log, identified by a container ID generated sequentially, and include references to data containers. An index is maintained to map segment fingerprints to container IDs. Upon starting a migration to a second cloud, a checkpoint is created identifying a container ID at a head of the log. During migration, the index is updated to map fingerprints of migrated segments to new container IDs, and referencing new data containers having the migrated segments and written to the second cloud. A request to read a file is received. The index is examined to identify a container ID associated with a data container storing segments of the file. Based on the identified container ID and the checkpoint, the data container is accessed from the first or second cloud.
